I belive that the answer my be c but how they worded it made my probablitity calculations a bit harder.
Answer: 4.3
Step-by-step explanation:
11x2=22
22/3= 7.3
7.3-3= 4.3
Answer:
8-10 feet
Step-by-step explanation:
If the length of the carpet is two more than the width, the width can be expressed as x and the length can be expressed as x+2. This means that the area(x^2+2x) must be greater than 48 but no less than 80.
Now we can solve for both the maximum and minimum cases:
x^2+2x=48, x^2+2x-48=0, now we can factor, (x+8)(x-6)=0, and now we can use the Zero Product Property to find x=-8;x=6. Since we cant have negative width, x at least has to be equal to 6.
x^2+2x=80,x^2+2x-80=0, now we can factor, (x+10)(x-8), and now using the Zero Product Property to find x=-10;x=8, and since it must be positive, at most x can equal 8.
Now since the length is two more than the width, x, you add two to both of these values and get a range of 8-10 feet.
Question is Incomplete, Complete question is given below.
Mr. Jablonski's class is making fudge for a bake sale. Mr. Jablonski
has a recipe that makes 3/4 pound of fudge. There are 21 students in
the class. Each student uses the recipe to make one batch of fudge.
How many pounds of fudge do the students make?
Answer:
student made
of fudge.
Step-by-step explanation:
Given:
Mr. Jablonski recipe makes 3/4 pound of fudge.
Number of student in class = 21 students.
Each student uses the recipe to make one batch of fudge.
Hence to calculate Total amount of fudge student made we will multiply the amount of fudge used in recipe with Number of students.
Total amount of fudge student made = amount of fudge used in recipe × Number of students.
Total amount of fudge student made = 
Hence the student made
of fudge.
Well, I would just reverse it. It seems you just have to reverse the whole problem.
